UPDATED: Ngaiire's illness halted her NYE TV performance

Update Monday 12noon: New Year's Eve 2017-18 was meant to be a highlight on Ngaiire's career, but instead became a date of worry at a hospital bed.

The former Kadina High student was meant to be on stage at the ABC's New Year's Eve spectacular Countdown show, which produced higher than expected viewership numbers.

But Ngaiire had to watch the show instead from her TV at a room in a Sydney hospital.

She posted about it on her Instagram account on New Year's Eve.

"Unfortunately I won't be singing at The Sydney Opera House tonight for @abctv's spectacular Countdown," she said.

"Most of my festive season has been confined to this hospital bed surrounded by family sipping on cocktails of morphine, endone, codeine and Panadol due to a condition that doctors still can't diagnose."

That condition she has now confirmed to be four tumours in her liver while she is pregnant with her first child.

"Despite ending 2017 on a low it's been a pretty EPIC one for me behind the scenes. I've been stretched and challenged in ways I never imagined and I'm nervous and excited to share some of the best art I've ever created in 2018. HNY friends. Thanks for being super supporters always," she included in thet post.

Original story: AUSTRALIAN artist and former Lismore resident Ngaiire has shared a serious diagnosis by her doctors plus broke the news that she is pregnant with her first child.

In her Instagram account, the singer revealed doctors had found tumours in her liver.

"Dear everyone. Thank you for your well wishes. After three weeks in hospital my surgeon has identified that I have four tumours on my liver," she posted.

"Because I've been blessed to carry this beautiful bodacious baby boy (surprise) it's difficult for doctors to decipher if the tumours are malignant or benign at this stage which will mean a lot of progressive monitoring every week.

"Baby boy is very happy and healthy at the moment but here's hoping I won't need to deliver him before he's full term if the tumours end up being cancerous.

"When you are that age you shouldn't be crying over being in hospital for days on end, you should be crying for a bruised knee.

"People kept telling me that I needed to fight and be strong and I had no idea what that meant, but I somehow managed to muster up some a version of what my parents were asking me to be, and it became the foundation of who I became as a person."

The post online also broke the news she is expecting her first born.

Fans reacted immediately to the news using social media to offer love, support and well wishes for the artist.
